sLInINofv WINDOW AND iTs'rItAiviE.

Y T all whom t mag/lconccrn.:

Be it known that I', W'iLLiAiirADoLriiUs WILSON, a subject of His Majesty, the King of Great Britain and Ireland, residing at 3 Rawlings road7 Birmingham, England,have invented new and luseful Improvements in Sliding W'indows and Their Frames, ofV

which the followingis a specication.

This invention has; reference to sliding windowsand the window frames therefor of that kind in'which both sashesare mounted to turn on side pivots aboutV midway of their height,v on vertical runners adapted to moveA up and' down in vertical side grooves of thev sashv frame, and the sash'ncords are fixed to these runners and are either so arranged Vwith their pulleys that the weight. of one sash counterbalances the weight of the other sash,` or the cords pass lover pulleys tothe usual counterbalance weights. With this arrangement both sashes can be turned on'the sidepivots of theirrunners and cleaned in side and outside from the insidel of the room. The pivoting of the sashes to the runners in the-present instance is effected by the former being furnished with pivot pins which engage with slotted plates fixed to the sides of so. as to enable theoutside of the glassto be 5ov A bottom sashes can whenk in their lower jposicleaned from inside the room. In asimilar manner the top sash vcan be lowered and the bottomsash raised, and when the 'top sash' is sufliciently lowered and the Yhinged side strips are turned back as aforesaid, the top sash vcan be similarlyvturned about its side pivots-toy enable itsy glass to be cleaned from insidethe room; thus both the inside and the outside 'of the glass of both the 'top and tion be cleaned from theinside ofthe room. My invention also comprises vspecial arrangements of the pulleys andcoi'ds to be combined with the said window made with the sliding and swinging sashes as aforesaid so Specification of Letters Patent.

as to insure yboth sashes.moving together even if the vtop sash should stick in itsguides.

Moreover l provide improved means whereby the counterbalanced and swinging sashes can readily beremovedfrom their Y runners without disturbingthe latter and moreover said sashes `can be securely, locked when open to various amounts in addition to being .locked when' closed.

' gage in bearingsin 'vertical runners 2, 3,

adapted to move upl anddown in vertical side grooves i of thesash frame B andthe also a sectional side elevation of Fig. 7' is asectional side elevation of the ',f

two sash cords, 6, are. fixed to these runners 2, 3, instead offbeing iiXed to. the sash A as would be the usual arrangement. The lowerV portions Yof .the two vertical vwooden side .strips `of the window frame which usually overlap the top 'and bottom sashes and form the front sides of the grooves 4L, up and down which the-front sash A slides (see Figs.4 l and 2) are for the depth-of the lower frame each made of two pieces marked respectively 8 and 9 of which the Y strips 8 are screwed or otherwise fixed to the front of the window frame B so as to overlap the sides of the runners 2, 3, and the strips 9 are hinged at 10 to these strips 8 so that when the strips 9 are turned against. the sides of the bottom sash as in Fig. 2, they maintain the bottom sash in its vertical position, but when folded back against the window frame as in Fig. 1 and as shownby dotted lines in Fig. 2, the bottom sash can be turned about its side pivots 1 and be reversed in position as shown by dotted lines in Fig. 5- so that the top rail l1 of the bottom sash A will vnow be at the bottorn, and the bottom railVA 12 of the bottom l sash will now be at the top, and the outsideY of the glass will be inside and can readily be cleaned from the inside of the room. Then when the bottom sash A has been turned back to its propervertical position and the strips 9have been turned back to their normal position against the sides of the sash and secured as by `flush bolts or other means, the sash A is ready for moving up or down.

The top sash C is similarly constructed, that isV to say somewhere about midway of its height the sash C is mounted on side pivotslS which are carried by runners 14, 15, which slide between the parting bead 16 of the window frame and the outside beads 17 of the same and to these runners Y14, 15, the ends of the sash cords 5, 6, are'iixed. Now when it is vdesired to clean the top sash' C'the bottom sash A is first raised up as far as it will go as shown in Fig. 6 and the top sash C is pulled down as far as possible, asVv shown in Fig. 6. Now -when the two side strips 9 at the front of the window frame have been turned back onv their hinges as aforesaid as is indicated by dotted lines in Fig. 2 the top sash C can be turnedon its side pivots into the room as in Fig.'6 V

and reversed in position so that its top rail 118 will now be at the bottom and its bottom rail 19 will be at the top and the outside of the glass will be inside, so that it can readily be cleaned from the inside of the'room, and when so cleaned, then the sash C can be turned back to its normal position and slid up as aforesaid, as shown in Fig. 1. The portions 16 of the two parting beads which areimmediately between the two runners 2 and 14 and 3 and 15 extend from the top to the bottom of the window frame 1, but the two. narrow portions 20, between the two sashes only extend from the top of the frame to the top of the top rail of the bottom sash so as not to interfere with the sashes swinging on their sidepivots as aforesaid.

As before stated, the sashes A, C, can be counterbalanced asusual by cords passing over ordinary sash,l pulleys to counterbal ance weights in pockets at the sides Vof the cords 5, 6,'fof the two Vrunners 2, '3, of the Y bottom sash A passing over top pulleys 21,

22, in the window frame and the ends of the cords 5, 6 being connected to 'the runners v 14, 15, of the topsash, C as in the arrange-V nient illustrated in Figs. l, 5 and 6, so that in this case no counterbalaneeweights are requiredand the window'frame B isless costly to construct besides saving the cost` of the sashweights. In this arrangement of my invention the sashes A and C move simultaneously, one sash going up while the other sash goes down and iny Yorder to'prevent adirect draft into the room from the bottom sash A when the top sash is moved down over a shorty distance for top ventilation, a horizontal flap t'm'a-y be provided and hinged to the bottom of the inside of the window frame'B (see Fig. 1), this strip being adapted to turn up Vand lclose the nar'- row short space there would be between the bottom of the bottom sash A and the'bottom` ofthe window frame B when the bottom sash is raised for ashortdist'anceto permit of top ventilatioii'over the top sash as afore` Y said, this horizontal flap 4:5 being adapted to" turn up between the two side strips .and being secured by flush bolts or any convenient means as will readily be understood. Y In a modification of my invention instead of the cords 5, @whichconnectthe'vertical runners of thebottom sash tothe vertical runnersof the top sash passing over the side pulleys 21, 22, on the top of the window frame so as to enable one sash to counter- .one and the'samel horizontal pin 25' at about midway of the height of the frame orother.-

balance the other' one as aforesaid,the said wise about level with where'the top rail of the bottom'sash A meets the bottom rail of the top sash' C when both sashes are closed. The runners 14;, 15, of the top sash are con`r nected to the runners 2, 3, ofthe bottomA sash Y at each side bytwo stranded wire cords or the like, one ofwhich namely-26 is fixedy as at 27 to the bottom of the runner 14 ofthe top sash and passes over the side pulley 23, and has its other end 28 fixed to an attach:

ment on the bottom of the runner 2 ofthe bottomk sash and the other stranded wire cord 29 orthe like has one end 30 fixed to l the top of the runner 14 of the top sash and passes under the other pulley '24 and then turns up and is fixed at 31 to an attachment on the top of the runner 2 of the bottom sash; thus by this arrangement the Vsashes A and C -will counterbalance each other and the bottom sash A cannot` be of the wire such as the end 30 in Fig. 7 be-` ingformed into a loop and permanently fixed as by a cross screw to the top end of the runner 14 and the other'end of the wire being soldered or otherwisevfixed to a short Vscrew threaded wire stem 34 which passes through a slotted or other hole ina plate fixed to the other runner 2. A nut 86 is provided on thel wire 3.4 by which the wire can be lengthened or shortened`within certain limits to take up any stretch in the wire. This tensioning device is well known kand I make no claim to it.

In order to fasten the sashes and prevent them'from being opened from the-outside a peg may be provided'in one or both sides adapted to pass'through anyy one of a series of holes in the hinged vertical wooden side strips 9 of the frame into a corresponding hole or holes in the runners. 1.-

In order to facilitate the removalvof the sashes from the runners the side pivotsvon the sashes-are preferably each made with laV l' head 38 and a narrow neck adapted to pass through a side slot 39 in a platel 40 (see Fig.v which is ixed to the face of the runner, said necks engaging in bearings at the bottom o-f the slots. Thus to remove the sash from its runners thel sashY must be raised sufficiently` for the hingepins to pass out of the side slots, but in order to secure thepivot pins in the slots until the sash is y turned it is preferred for the top and. bottom ends of each runner to be Vprovided With laterally projecting inclinedplates such as 41, 42, (see Figs. 3 and 4), thesebeing arranged toengage with the corresponding rabbets 43, 44, formed on the sides of the sash and. thus prevent the sash from being,

lifted independently of the runners unless the sash is Vturned out of its normal position parallel with the runners. Y

l/Vhat I 4claim as myinvention and desire to secure vby Letters Patent is Y The combination with a window frame,` of an upper and lower sash 4mounted for` sliding movement in said frame, a pair of independently revoluble pulleys mounted at the side of the frame intermediate its ends,

.. a fiexible strand led under one of the pulleys and having its ends connected to the upper parts of Vthel sashes and a second flexible strand led over the other pulley and having its ends connected to the lower parts of y the sasheswhereby a vmovement of either sash compels movement of the other sash.

Ink testimony whereof I have signed my name to this specification.
